think: 30 thousand + 5 thousand 
b. 200,000 + 1,000 = 
c. 400,000 + 30,000 =  d. 710,000 + 40,000 = 
e. 300,000 + 700,000 =  f. 700,000 + 70,000 = 
5. Add and subtract, thinking in whole thousands.
a. 35,000 + 5,000 =  b. 711,000 + 10,000 = 
c. 420,000 + 30,000 =  d. 700,000 – 70,000 = 
e. 300,000 – 60,000 =  f. 1,000,000 – 200,000 = 
g. 30,000 – 5,000 =  h. 200,000 – 6,000 = 
i. 723,000 – 400,000 =  j. 500,000 – 1,000 = 
6. On the number line below, 510,000 and 520,000 are marked (at the “posts”).
Write the numbers that correspond to the dots.
7. Make a number line from 320,000 to 340,000 with tickmarks at every whole
thousand, similar to the one above. Then mark the following numbers on the
